I have downloaded a raster surface (SRTM) with pixel size equals to 30*30, and I want to use that surface as a geostatistical layer for further analysis. Is there any available tool that converts directly raster surface into geostatistical layer? I am using ArcGIS 10.4.1.
Therefore, if it does not exist any available tool, this methodology sounds accurate? 1) Considering the extent of the raster surface, I will construct grid points every 30 meters. 2) Using extract values to points tool, I will attach Z coordinates as attributes of grid points layer. 3) Interpolation of grid points using IDW tool(geostatistical analyst toolbox), gaining a new updated SRTM.
How accurate is this procedure comparing the raw SRTM with the modified SRTM that was developed through grid points?
